I've got a modified s49 RDESIGN t5 manifold I'll sell it's had the turbine housing cut off and a cast t3/t4 adapter with external waste gate flange been welded to manifold and it's been done properly with correct nickel cast welding wire we pre heated and slow cooled it in vermiculite so it has zero cracks looks great with the gt3582R turbo and 38 mm tial gate 3" dump and screamer plumbed back into the dump. I'll sell you the whole shooting match if ya interested I'll part with the whole kit manifold ,oil/water lines , turbo ,waste gate and dump for $800 it's all un used I never got to run it on the s40 but had plans of wacking it on the 2011 v50 RDESIGN I bought not long ago for a steal ,only paid 4 grand off grays online so I got no reserves on going big with it but saying that I got no problems modifying another t5 manifold either so it here if ya interested
